A nanorobot swarming algorithm based on bacteria foraging optimization to eradicate cancer cells

Multi-robot cooperation is a critical technology for nanorobotics and nanomedicine. This paper presents a nanorobot swarming algorithm based on Bacteria Foraging Optimization with the aim of eradicating cancer cells in blood vessels. In the algorithm, each nanorobot is considered as a bacterium with specified chemotaxis and swarming behavior. A simulation environment reflecting the property of concentration, diffusion-rate and evaporation-rate of chemical substance is established in the paper. And simulations have been conducted to evaluate the effectiveness of swarming algorithm in a local field of blood vessel.
